Spreadness of each condition in 2-D isomap spaces, both k-nearest neighbor approach (a) and the epsilon-based approach (b). In k-isomap, the spreadness in Neutral: \(65.61\pm 2.74\), Maintain: \(79.51\pm 3.64\), Reappraise: \(88.67\pm 2.27\); in \(\varepsilon\)-isomap, the spreadness in Neutral: \(45.43\pm 2.09\), Maintain: \(55.78\pm 2.27\), Reappraise: \(64.30\pm 2.09\). Both suggest the Thought Chart is more scattered as the task condition becomes more complex. Significant findings in group t test are indicated with **\(p < 0.01\) and *\(p < 0.05\)
